Output Specifications
Specification
1769-OF2 (Series B or later)
Analog Normal Operating Ranges
(1)
(1) The over- or under-range flag will come on when the normal operating range (over/under) is exceeded. The
module will continue to convert the analog input up to the maximum full scale range. The flag automatically
resets when within the normal operating range.
Voltage: ± 10V dc, 0 to 10V dc, 0 to 5V dc, 1 to 5V dc
Current: 0 to 20 mA, 4 to 20 mA
Full Scale Analog Ranges
Voltage: ± 10.5V dc, -0.5 to 10.5V dc, -0.5 to 5.25V dc,
0.5 to 5.25V dc
Current: 0 to 21 mA, 3.2 to 21 mA
Number of Outputs
2 single-ended
Bus Current Draw (max.)
120 mA at 5V dc
120 mA at 24V dc
(2)
(2) If the optional 24V dc Class 2 power supply is used, the 24V dc current draw from the bus is 0 mA.

0 to +10V dc: Sign + 14 bits, 0.64 mV
+4 to +20 mA: Sign + 14 bits, 1.28 µA
+1 to +5V dc: Sign + 13 bits, 0.64 mV
0 to +20 mA: Sign + 14 bits, 1.28 µA
Conversion Rate (all channels) max. 2.5 ms
Step Response to 63%
(3)
(3) Step response is the period of time between when the D/A converter was instructed to go from minimum to
full range until the device is at 63% of full range.
